The problem revolves around the syscall.o module. To workaraound the bug, do the following: ar -x /lib/libc.a syscall.o cerror.o Then redo the link steps of perl by ADDING these two .o files to the command line. In this way, the bug in syscall.o will not manifest itself since the procedurte it wants will be close enough in the resultant address space. I don't work for the compiler group, I just know someone there who helped out when I encountered the problem independently.

I had exactly the same problem. The reason for this error is that syscall
has a branch to $cerror at the specified location (0x3c) and I guess that
the branch is too long (bytewise) for the assembler. (NOTE I'm only guessing
since I don't understand HPPA).
The fix we made was to extract syscall.o and cerror.o from /lib/libc.a
(ar x /lib/libc.a syscall.o cerror.o)
and put these in front of the other objectfiles when linking, thus
bringing syscall and cerror "closer together".
That is:
cc syscall.o cerror.o [ rest of .o ] -lm -ldbm -o perl
Everything worked nicely.
I really don't know if my "explanation" makes any sense to you but the point
is that it works (or at least seems to work).
Further info from somebody that understands HPPA would be greatly
appriceated.

The problem is that the linkage between syscall and cerror uses a short branch instruction rather than a long one. If you refer to syscall explicitly in a large binary this can results in cerror being out of range. Loading them explicitly together works around this problem. In 7.0 the branch instruction has been fixed. The problem is more likely to be that public consumption was not foreseen & tested, not so much that it was forbidden. Note that I'm not speaking for HP in this case, this is just my own understanding.
